> It's not size, but power. Twitter's curation algorithms have massive unilateral influence on public opinion (reaching far beyond its own user-base) probably including the ability to sway national presidential elections. I'm not aware of any utility companies with such power.
And most of the cases I'm aware of where they've used that power is to suppress viral lies, which is a good thing. Even then they were late pulling the trigger.
> Moreover, social media introduces an entirely new dimension: it's multicast. Your telegraph or phone call conveyed information to 1 other party at a time. A Tweet can be seen by millions or more. The volume of communication on social media dwarfs that of other channels.
And that's what's dangerous about them: the filter got removed from broadcasting. People like to talk about filters like they're bad things, but that's not true. They're in fact a vitally necessary function to increase the signal-to-noise ratio (for instance: what is peer review? Answer: a filter). when you don't have filters, ideas spread in proportion to how quickly they can multiply, which isn't a good thing, because a lot of fast-spreading ideas are akin to cancer, and do nothing except weaken or kill the host.
If Twitter's to avoid killing its host, it needs an immune system to filter out those cancerous ideas.
